MERGERRZING sorrow Patented Feb. 26, 1907.-

Application filed may 27, 1903'. Serial No. 158,959.

Be it known that I, 'LUre-fCIroLLINA, a subject of the King of Italy, residing at Rivarolo Ligure, ltalygha've invented certain new and useful Improvements in Machines for Mercerizing Cotton, &c., of which the follow- 1 ing is a full, clear,-and exact description The object of my invention islto prov1de a cheap and efficient apparatus forthe mercerizing of cotton, whereby the cotton is given a uniform brilliancy, practically that of silk. This I accomplsh by giving to the hanks or loops of yarn a perfect and uniform degree of tension before they are dipped into the bath of caustic-soda solution, and while this may be accomplished by various devices and mechanisms 1 have found exceedingly ellicient, and prefer to use to bring about such result and carry into operation my improved method of mercerizing, the apparatus shown in the drawings and hereinafter described.

My-said invention is fully shown in the following specification, of which the accomp anying drawings form a part, wherein similar numerals of reference designate like'or equivalent parts'wherever found throughout the several views, and in which- Figure 1' is a view of the machine or apparatus which I prefer to use to carry out my process of mercerization. Fig. 2 is a front view of such apparatus, partially in section; and Fig. 3 is a plan view of the rotating cylinders of such apparatus and their supports.

The rincipal frame of the machine consists of four uprights 1 usually planted in the ground and united rigidly at the top by two side cross-bars 2, a front bar 58, and a rear bar 4. To this main frame are attached the various mechanisms necessary for the workingrof the machine. I

he skeinsto be treated are supported by I two series of metallic horizontal coupled cylinders on identical vertical planes. The superior cylinders 5 are supported at their osterior extremities by bearings attache to the cross-bar 4 and carry the fixed helicoidal wheels 6, which are actuated by the endless screws 7 (of which in Fig. 2 only one is shown for simplicitys sake,) attached to'the axle 70, which carries the driving-pulley 9. On

their anterior ends the cylinders 5 end in a conical point which penetrates the cross-bar- 3. The'inferior cylinders 10 at the posterior ends of their axes bear toothed wheels which are put in gear one with the other and receive the motion from the superior cylinders 5 through conical toothed wheels 12 and 13, united by means of a vertical shaft 14 capableof vertical reciprocation. These inferior cylinde'rslO are supported at their posterior cross-bar 16. h

The rods 17 are vertically reciprocated by the female screws 18, which are provided ex- 20 and the conical gears 21 a vertical motion of translation is transmitted to the cross-bars 15 and 16, thus changing the position of the cylinders with reference to the cylinders 5.

The conical gearings 21 are united together by means of the shafts 22,. '23, and2 1. The middle shaft 23 carries the two toothed wheels 25 and 26, which gear, respectively, with the toothed wheels 27 and 28 on the same shaft, on which are placed the fixed pulleys 29 and 30 and the loose pulleys'31. By means of a belt acting on the ulley 30 the motion is transmitted to the our endless screws 20 in the proper direction to lower the two crossbars 15 and 16, so as to force the cylinders 10 away from the cylinders 5. By shifting the belt onto the pulley 29 reverse motion .of increased velocity is transmitted to the endless screws 20, so as to lift up the crossbars 15 and 16 and with the latter also the" cylinders 10.

' Y The front cross-bar 3 is so arranged as to swing through an arc of more than ninety degrees around the pivot 32 of the hinge 33 of the upright 1, and the against the other upright 1 and is fixed by means of a spring-bolt 35, which enters into a guide in said upright. The inferior crossbar 16 is also arranged so as to turn round the axle 17, as shown 1n Fig. 2, through an arc of more than ninety de ees with the cross-- bar 3, to which it is united by means of the shaft 36. r

To operate this apparatus and carry out my improved process of mercerization, the apparatus shown is operated as follows: To load the machine with the cotton skeins, the workman with his lefthand frees the sprin bolt 35 from the upright in which it is insorted and with his right hand he grips the handle 36 and pulls toward him the two crossends in bearings attached to the cross-bar 15 and their anterior conical ends reset in the ternally with helieo'idalcrowns. By moving these crowns by means of the endless screws free end 34 leans bars 3 and 16, thuswidening the space between them sufficiently to allow of the freely putting in its place of the end of the cotton on the cylinders 5 and 10. The workman then pushes back into place the cross-bars 3 and 16, and by means of the lever 37 shiftsthe belt from the loose pulleys 31 onto the fixed pulley 30, thus putting into motion the various gearings and by means of the cylin- :lers and 5 giving a uniform tension to the various skeins of cotton. has reached the utmost limit of the unitarian resistance of the cotton, a stop attached to the cross-bar strikes the projecting piece 38, Fig. 2, and compels the lever 37 to push the belt on the loose pulley 31, next to the fixed one 30. The projection 38 is on the shaft or p.11 62, which is a plied tothe extremity of the lever 65 an is controlled by a screw 64. The lever 63 is joined to the lever 65 66 67. The latter acts on the rod 68, controlled by a spring, and causes the moving of the guides for the belts. The rollers 69 help the moving when the cotton has a convenient tension, and bypushing the belt on the pulley 39 this moves the two endless screws 40, which are in gear with thehelicoidal wheels 41, wedged on the shafts 59, which are attached on the uprights 1. On

said shafts 59 are securedthe gear-wheels 60,

which gear with the toothed bars 61, applied to the recipient 42, containing the liquid with a solution of caustic soda, which recipient, by means of the motion of the endless screws 40, is lifted up to the point in order that the cylinders 10, with the cotton, may be immersed in same. Putting the cylinders 5', and consequently also the skeins of cotton, into motion by means of the pulley 9 the cotton will of course be dipped for a suitable time,

- which ordinarily amounts to a few minutes.

After the dipping by working the pulley 43 the recipient 42 is lowered and covered with its cover 44, the latter being provided with toothed bars 45, which gear with the toothed wheels 46, moved by means of a--belt from the pulley 47, and the cotton is then washed. For this purpose the injecting-valve 48 receives steam from aboiler and injects it into the injector 49, usually of the Gifi'ard type, where the cold water is drawn in by means of the cock 50. The water is pushed by the steam under a pressurev of ninety ounds through the injector into the -recip1ent ,51 and by mixing up with steam is heated to a temperature of over From the recipient 51 the warm. water is conveyed to the i pipe52, provided with a largenu'mber of small oles from which it is sprayed against the cotton while the latter'lis mo Under and against the metallic cylinders'which carry the cotton are pressedtightly the rubber cylinders 53 by means of the spiral springs 54, attached to the cross-bars 2, which push upward the ends of the rods.55, regulated by When the tension screws which sustain the cross-bars 57, susver 37 from the loose pulley 3 1 to the fixed pulley 29 which will impart a very rapid motion by means of its gearings to the endless screws 20, uplifting the cross-bars 1 5 and 1 6, and with them also the cylinder 10, so that the tension process. of mercerization being thus completed, the operator then displaces the cross-.

bars 3 and 16 from their places and easily frees the mercerized cotton from the machine.
